[0031]
As shown in FIGS. 3 and 4, when the switch operation unit 5 is swung in the retraction direction (arrow A2 direction) manually or automatically by the user and changed to the switch retraction position M2, the table of the switch operation unit 5 is displayed. The exit surface 5f is set to overlap the holding portion 10 of the base 1 in the vertical direction. This is because θ1 = θ2 or θ1≈θ2 is set as shown in FIG. If the switch operation unit 5 and the holding unit 10 overlap each other as described above, the back surface 5r of the switch operation unit 5 faces upward, and the lateral space W1 of the toilet seat 2 is formed as shown in FIG. The volume increases. Thus, since the volume of the space W1 increases, it is advantageous in securing the spacer around the toilet seat 2 even in a narrow toilet room.
[0032]
According to the present embodiment, as shown in FIG. 1, when the switch operation unit 5 is swung in the deployment direction (arrow A1 direction) manually or automatically by the user and changed to the switch use position M1, the switch operation is performed. The switch 7 provided on the exposed surface 5f of the part 5 is exposed so as to face upward. For this reason, the user can operate the switch 7 of the switch operation unit 5.
[0033]
As described above, when the switch operation unit 5 is swung in the unfolding direction (arrow A1 direction) and changed to the switch use position M1, the tip 5b of the switch operation unit 5 is moved from the toilet seat 2 as shown in FIG. The toilet seat 2 faces outward, in particular laterally outward, so as to be separated in the width direction. That is, as shown in FIG. 2, the center line K2 of the switch operation unit 5 expands toward the front with respect to the center line P1 of the toilet seat 2 in the front-rear direction. That is, as shown in FIG. 2, the switch operation unit 5 set at the switch use position M1 is expanded from the base end part 5a toward the front end part 5b. For this reason, it is advantageous to avoid interference between the leg of the user sitting on the toilet seat 2 and the distal end portion 5b of the switch operating portion 5. Therefore, when the user seated on the toilet seat 2 has a large height, it is suitable for a user (generally a male) who tends to sit on the toilet seat 2 with his legs widened.
[0034]
In general, for a user sitting on the toilet seat 2, the switch 7 is easier to operate if it is located in front of the user. In this regard, according to the present embodiment, when the switch operation unit 5 is swung in the direction of the arrow A1 and changed to the switch use position M1, the switch operation unit 5 is considerably more than the holding unit 10 as shown in FIG. The switch 7 on the exposed surface 5f of the switch operation unit 5 is positioned on the front side rather than the lateral side of the user. Therefore, the operability for the switch 7 is improved.
[0035]
However, as described above, when the switch operation unit 5 is positioned on the front side of the user seated on the toilet seat 2, when the switch operation unit 5 is fixed, the switch operation unit 5 obstructs the user's leg or the like. Easy to be. In this regard, according to the present embodiment, when the switch operating portion 5 is swung in the retracting direction (arrow A2 direction) and changed to the switch retracting position M2, the distal end portion 5b of the switch operating portion 5 is retracted from the toilet seat 2. The switch operation unit 5 overlaps the holding unit 10, and therefore the switch operation unit 5 is not positioned in front of the holding unit 10, so that the tip 5 b of the switch operation unit 5 interferes with the user. It is advantageous to suppress Since the switch operation unit 5 can be prevented from interfering with the user in this manner, it is advantageous for extending the exposed surface 5f of the switch operation unit 5 to ensure a large operation area. As a result, it is advantageous to increase the size of the switch 7 (switches 70 to 74) provided on the exposed surface 5f of the switch operation unit 5, and is suitable for use by the elderly.
[0036]
As described above, when the switch operation unit 5 is swung in the direction of the arrow A1 and changed to the switch use position M1, the switch operation unit 5 extends considerably forward from the holding unit 10, so that the extension amount is small. When it is large, the user's finger sitting on the toilet seat 2 may not easily reach the switch 7 of the switch operation unit 5. In particular, when the user is seated on the rear side of the toilet seat 2, the user's finger may not easily reach the switch 7 of the switch operation unit 5. In this regard, according to the present embodiment, as shown in FIG. 1, when the switch operating portion 5 is swung in the direction of the arrow A1 and changed to the switch use position M1, the exposed surface 10f of the holding portion 10 is substantially horizontal. However, the exposed surface 5f of the switch operating portion 5 is disposed obliquely upward so as to be upward as it goes from the proximal end portion 5a to the distal end portion 5b. Thus, when the switch operation unit 5 is disposed obliquely upward, even if the user is seated on the rear side of the toilet seat 2, the user's fingers can easily reach the switch 7 of the switch operation unit 5. Thus, the operability of the switch 7 of the switch operation unit 5 is improved. Further, since the switch operation unit 5 is slightly inclined upward, the visibility of the switch operation unit 5 from the naked eye of the user sitting on the toilet seat 2 is improved, and the switch 7 of the switch operation unit 5 is visually recognized. The advantage which becomes easy to do is acquired.
[0037]
Further, when the switch operation unit 5 extends considerably forward from the holding unit 10, there is a possibility that the urine droplets may adhere to the switch operation unit 5 when the user urinates in the toilet while standing. According to this embodiment, when the switch operation unit 5 is not used, the switch operation unit 5 is folded and changed to the switch retracted position M2 as shown in FIGS. At this time, the front surface 5f of the switch operation unit 5 is reversed. That is, the switch 7 of the switch operation unit 5 is arranged downward and is hidden. Thus, if the switch 7 of the switch operation unit 5 faces downward and is concealed, it is advantageous to avoid the problem that foreign matter such as urine droplets and dust adheres to the switch 7 on the exposed surface 5f of the switch operation unit 5. . Therefore, it is advantageous to maintain the switch 7 on the exposed surface 5f of the switch operation unit 5 in a sanitary manner. At this time, as can be understood from FIG. 3, the switch 8 having a low use frequency of the holding unit 10 is covered with the switch operation unit 5 on the upper side thereof. This is advantageous in avoiding the problem of foreign matter such as dust. Therefore, it is advantageous for improving the hygiene of the switches 7 and 8 and preventing failure.
[0038]
In general, defecation is performed while the user is seated on the toilet seat 2. When washing the buttocks part of the human body after defecation, the user presses the switch 70 for washing the buttocks part of the switch 7 in a state where the switch operation unit 5 is set to the switch use position M1.

Then, since the water of the hot water tank 44 is fed to the first nozzle 41, the first nozzle 41 moves forward toward the local area of the user's bottom due to the water pressure, and the unillustrated water ejection hole of the first nozzle 41 that has advanced. Wash water is spouted out toward the buttocks, and the buttocks are washed. When the cleaning of the local area of the hip is completed, the user operates the stop switch 74 of the switch operation unit 5. Then, the ejection of the washing water from the first nozzle 41 is stopped, and the water pressure acting on the first nozzle 41 is reduced or released, so that the first nozzle 41 is retracted to its retracted position by the return spring.
[0039]
Further, when washing the female local part of the human body, the user sitting on the toilet seat 2 in the state where the switch operating part 5 is set to the switch use position M1, the female local part of the switch operating part 5 with fingers or the like The washing switch 71 is operated. Then, the water in the hot water tank 44 is supplied to the second nozzle 42. Accordingly, the second nozzle 42 moves forward toward the female local area due to the water pressure, and the wash water is ejected toward the female local area from the water ejection hole of the second nozzle 42 that has advanced, and the female local area is washed. When the cleaning of the female part is completed, the user operates the stop switch 74 of the switch operation unit 5. Then, the ejection of the washing water from the second nozzle 42 is stopped, and the water pressure acting on the second nozzle 42 is reduced or released, so that the second nozzle 42 is retracted to the retracted position by the return spring.
[0040]
When drying the buttocks area and the female area after washing, the user operates the switch for discharging hot air from the switch operation section 5 with fingers or the like while the switch operation section 5 is set to the switch use position M1. 72 is operated. Then, warm air is blown out from the warm air generator 43. In order to end the hot air blowing, the user operates the stop switch 74 of the switch operation unit 5.
[0041]
